The Impact of HTTP Status Codes on SEO


When it comes to search engine optimization, even the smallest details can have a significant impact on your website's performance. One of these seemingly minor details is the HTTP status code, which provides important information about the status of a web page to both search engines and users. In this blog post, we will explore what HTTP status codes are, their impact on SEO, and how you can ensure that your website is using them correctly.


HTTP status codes are three-digit numbers that indicate the status of a web page's request-response cycle. There are five different categories of HTTP status codes, each with its own specific range of codes. The most common HTTP status codes are 200, 300, 400, and 500. A status code of 200 means that the request was successful, while a 300 status code indicates a redirection. A 400 status code means that the client-side request was invalid, while a 500 status code indicates a server-side error.

The most important HTTP status code from an SEO perspective is 404, which means that the requested page could not be found. When search engines encounter a 404 error, they assume that the page is no longer available and will remove it from their index. This can lead to a decrease in your website's search visibility and overall traffic. To mitigate this, it's important to ensure that your website returns a proper 404 error page that includes helpful information and links to other relevant pages on your site.

Another HTTP status code that can impact your website's SEO is the 301 redirect. This code indicates that a page has permanently moved to a different URL, and the old URL is no longer available. When search engines encounter a 301 redirect, they will transfer the page's authority and backlinks to the new URL. This can be beneficial for your website's SEO, as it ensures that your content remains accessible and maintains its search rankings.

In contrast to the 301 redirect, the 302 redirect is a temporary redirect that indicates that the requested page has moved temporarily to a different URL. However, search engines may treat a 302 redirect as a 301 redirect if the redirect remains in place for an extended period. As a result, it's important to use 302 redirects sparingly and only when it's truly temporary.

Finally, another HTTP status code that can impact your website's SEO is the 503 status code, which indicates that a server is temporarily unavailable. When a search engine encounters a 503 error, it will temporarily remove the affected pages from its index until the server becomes available again. While this can result in a short-term drop in your website's traffic and search visibility, it's important to use the 503 code when necessary to prevent other server-related issues that can be detrimental to your website's performance.



As we've seen, HTTP status codes are an important component of website optimization that can have a big impact on your website's SEO. By understanding the various codes and how they work, you can ensure that your website is returning the proper codes in response to different requests. With a little time and effort, you can ensure that your website is optimized for search engines and users alike.
